Dc. Che et al., FLUORESCENCE EXCITATION-SPECTRA AND QUANTUM YIELD IN VACUUM-ULTRAVIOLET PHOTODISSOCIATION OF CF3CN, Chemistry Letters, (1), 1994, pp. 133-136
The fluorescence excitation spectra of CN(A,B-->X) and CF3 (2A'1-->1A'
'2) and the quantum yield for the CN(B) radical formation were measure
d in the photodissociation of CF3CN in 105-135 nm. The quantum yield f
or the CN(B) radical formation was found to be only a few percent. The
similarity in the excitation energy dependence of CN(B-->X) and of CN
(A-->X) indicated a common dissociation mechanism via the 3s Rydberg s
tate of CF3CN for both states.
